Dual Core SU2300 Benchmarks vs Single Core SU3500? Acer 1410

[Rahul]

I am curious about the heat, noise and battery life of the SU3500 processor in the now discontinued 1410 models and processors in the new 1410/1810 models.

Wikipedia tells me that the SU3500 has a TDP of 5W whereas the other processors have a TDP of 10W.

Would this make a noticeable difference in fan noise, heat output, battery life?
Suppose I put the higher capacity batteries from the 1810T/TZ models into an SU3500 model to make things even. Would I get higher battery life from the SU3500, the other processors or around the same?

I know the order in which models would give me the best performance, but I'd also like to know the order in heat, noise and battery. Battery is more tricky since the higher end models have higher capacity batteries also.

Rahul,

My hunch, and I stress hunch very heavily, is that under normal usage, that the fan noise, heat output and battery life between the SU3500 and SU2300 will be very very similar. SU2300 might be a little bit less than the SU3500 in terms of battery life, but nothing huge.

As stated often, the "Max TDP" values only occur when you're pegging the CPU near or at 100% of usage. SU3500 having a 5.5W TDP and the SU2300 having a 10W TDP; a difference of 4500mW.

Both the SU2300 & SU3500 are fabbed with the exact same architecture, VID Voltage Range, etc. and normally with these types of CULV and Atom-based machines, the CPU usually isn't the largest user of power from the machine. It's the combination of the LED/CCFL backlighting, chipset power requirements, WiFi, Bluetooth, HDD, IGP's, etc.

Cheers,
Kermee

For the record here's my 3DMark results for my Acer Aspire 1410 SU3500 1.4GHz 2x2GB 800 5-5-5-18:

3DMark05:

Here are my results(800MHz 6-6-6-18)
[Acer Aspire 1410/1810t/1810tz] Timeline Tweaks (2)
[Acer Aspire 1410/1810t/1810tz] Timeline Tweaks (2)

@1.4GHz with Vista drivers I get 1673 points in 3D Mark 03 and 625 points in 06. But as I said in that post, Source games need Win7 drivers to get the most out of it.

800MHz @ 6-6-6-18 is rather pointless. Sure you can tell other people how you're running 800Mhz, but the latencies are actually longer (slightly) @ 800MHz (6-6-6-18) than they are @ 667 (5-5-5-15).

I just posted the latencies so that people realize that lower latencies don't improve performance

my su2300 gateway 11.6 netbook with the 4500MHD chipset and 2GB ram got 589 on 3d mark 06. Does that mean it is better than the su3500 with its 3mb cache?

589 vs 572 is hardly anything to consider "better" ~ 3%. It could be due to cache or fact that you get a little advantage out of the dual core. I dunno. The SU2300 is a good chip and has the advantage of having dual core.

Right, it is cheaper, and I am running 2 gigs vs the su3500 running 4. either way, i am impressed by how fast 7 runs on it and when i bought it for 415$, the su3500 was $500.

[HTWingNut]

Whoa. I must have landed a bargain with mine for $350 + $35 rebate on the memory I bought, so less than $400 all said and done. I guess I should be happy.
